What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines available. It is made up of three main components. The bottom holds the water, and the middle is a filter-basket with a metal filter.
This machine was a huge success and helped to popularize the prosumer (home barista) espresso market. It features a 2.2L steam boiler, low pressure pre-infusion & 9 bar pressure for brewing.
Pressure
If you are an avid coffee drinker, you'll know that the pressure of your espresso machine is an important factor in the quality of your beverages. The pressure of your machine is essential in brewing excellent coffee whether you want a thick layer or the perfect balance of acidity and flavor.
BARs (Barometric pressure) is the force your espresso machine exerts on the grounds of the coffee while delivering high-pressure water. 9 BARs means that the espresso machine is forcing heated water through the ground coffee at a the rate of nine times the Earth's current atmospheric pressure.
The pressure of your espresso machine is important as it allows the water to move through the grounds of your coffee with the right speed and with the right intensity. If the pressure isn't sufficient, the oils and flavors will not be extracted properly. If the pressure is too low the dissolved oils and flavors will not be extracted properly.
You can regulate the pressure of your espresso maker by adjusting the screw on the espresso pump. Commercial machines and top-end home machines come with rotary pumps with adjustable pressure. For the less expensive home machines that have a vibrating motor, it is impossible to alter the pressure without DIY hacks. Companies like Cafflano however, are developing technology that utilizes Pascal's Principle to ensure pressure within the portafilter throughout the making process.
Temperature
Temperature is one of the most important aspects in the making of a good espresso shot. If the water is too hot, it could scorch the coffee grounds and result in an over-extracted bitter brew. The ideal temperature for extraction is about 200 degrees Fahrenheit, which allows the water to extract all of the desirable coffee flavors without scalding the grounds or over-extracting.
The best
espresso coffee machine machines feature the thermoblock, or thermocoil which heats the water and maintains it at a constant temperature throughout the extraction cycle. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system that continuously monitors the temperature of the water and adjusts as necessary, ensuring that the brew head stays at the ideal temperature to extract the coffee.
Most coffee lovers know that the temperature of the espresso machine is vital to brewing a great cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. To achieve this, your machine must have a good thermoblock or thermocoil and the boiler needs to be sized to the correct size.
It is also essential to pre-heat your
espresso home machine maker or portafilter before making a shot. Inability to heat your equipment is among the most frequent mistakes made by novice espresso makers. It is advisable to read your espresso machine's instructions before you begin using it for the first time.
Grind
A barista espresso machine must also provide a variety grind settings to give you the most control over your final cup of coffee. Some machines come with an analog pressure gauge, which looks cool and can help you learn about your brewing abilities. It is recommended to maintain the pressure of nine bars throughout the brewing cycle. Although this machine isn't hitting the mark, it's pretty close and will be able to serve you well.
A built-in burr mill is a nice touch. This feature is ideal for beginners because it eliminates having to buy an additional grinder. The stainless steel conical grinder has 18 settings, which range from "coarse to fine."
This grinder isn't as powerful as a standalone but it can help you get going in the right direction to making excellent espresso shots. It's easy to clean and you'll be able to stop the grinder during the grinding process to prevent accumulating a large amount of grounds on your portafilter while it is being crushed.
It's a beautiful and practical machine that will allow you to experience the joy of being a barista home. This is a great choice for those who wish to remember the thrill of pouring microfoam into their morning cup of coffee by locking the portafilter to the grouphead's head and tamping the coffee with precision. A bean to cup machine is an excellent choice to those who prefer convenience.
Water
Water can be a tricky thing to master. Finding the right balance is key. Too much can cause mineral deposits in your machine, however too little and you'll struggle get a rich cup of espresso.
The best espresso water has a low hardness and alkalinity level. This is best achieved by using a water filter system that bypasses all chlorine and adds an amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will ensure an ideal balance between hardness and acidity and avoid the need to decalcify.
Using high-quality filtered water is vital to your machine's longevity health and the flavor of the
coffee machines espresso it produces. Based on the type of use and the hardness of the machine, you should make use of a descaling product on a regular basis. The products are available in powder, liquid or tab form at most hardware stores.
